Hydraulic Plunger Device

ABSTRACT

A toilet plunger device relating to a hydraulic plunger that may be inserted into a toilet to create a seal beyond or below the siphon jet that, further, may employ pressurized water to dislodge a clogged toilet drain. The plunger includes an elongated carrier body with a coupling, a first flange, a second flange, and a resilient foam body. This assembly is connected to an elongated tubular wand that is connected to a trigger valve which, in turn, is connected to a source of pressurized liquid. The foam body is inserted into the toilet drain and creates a tight seal around the drain. The trigger valve then operatively releases a flow of pressurized liquid through the tubular wand and the elongated carrier body to break up debris and clear the drain.

FIELD OF THE INVENTION

The present invention relates generally to toilet plunger devices, and more particularly, relating to a hydraulic plunger device that may be inserted into a toilet to create a seal beyond or independent of the siphon jet that, further, may employ pressurized water to dislodge a clogged toilet drain.

BACKGROUND OF THE INVENTION

Previous toilet plunger devices typically employed a manual hand operated plunger, typically consisting of a rubber cup and stick to dislodge a clogged toilet drain. While the traditional suction cup plunger with a wide flat face may still be popular, it may be difficult to use these plungers on newer curved toilet drains.

Other hand operated cup plungers will not have the open face of the traditional plungers but, instead, are typically designed to fit the tubular curve-shaped toilet drains and often have a rubber flange extending from the bottom of the cup to allow for the plunger to fit in the toilet drain with a tighter seal on curved surfaces. These plungers still suffer from a great deal of slippage while in use and require additional pumping strokes to be effective.

Newer cup plungers have tiered-sections of rubber for the purpose of maintaining a better seal around the drain from all angles. In use, however, the pumping motion of these plungers often results in the undesired creation of waves, bubbling, and backsplash of the water within the toilet.

A newer spring plunger, with a bellows-shaped chamber, has a taller compression chamber and a funnel nose designed to be inserted into the toilet drain before plunging. The plunger therefore offers more pressure on the drain per square inch than standard plungers. This greater pressure that is created with every plunge is able to clear some of the most stubborn clogs. While spring plungers have the potential to be very effective, the size and shape of the plunger, namely the chamber, may prove to be cumbersome and difficult to use. For example, the chamber may remain compressed after several plunges, the chamber may turn inside out, and vigorous plunges may also result in backsplash. In addition, water and/or sewage which may have entered the chamber may not be completely removed from the chamber after use.

Hydraulic plungers using pressurized water are also known in the art. However, these plungers do not form effective seals in the drains.

Accordingly, there is a need for a toilet plunger that is capable of conforming to any toilet trap to provide a tight seal beyond or below the siphon jet in order to maximize the pressure that is to be applied to the blockage, while decreasing backsplash. Furthermore, there is a need for a toilet plunger that minimizes the manual operation that is needed with conventional hand plungers and for a toilet plunger that is easily cleaned.

SUMMARY OF THE INVENTION

The preferred embodiments of the present invention address this need by providing a hydraulic plunger capable of conforming to any toilet trap and capable of forming a tight seal beyond the siphon jet to maximize the pressure applied to the blockage, while decreasing backsplash and minimizing manual operation.

DETAILED DESCRIPTION OF THE INVENTION

With reference now to FIGS. 1 through 4 of the drawings, a new hydraulic plunger device embodying the principles and concepts of an embodiment of the present invention and generally designated by the reference number 10 will be described.

The hydraulic plunger 10 generally includes an elongated tubular handle or wand 12 configured to be connected to a source of pressurized fluid, such as water from a conventional water faucet, and a plunger head 14 that is secured to an end of the wand and through which the pressurized fluid is discharged. The plunger head 14 is positioned below the siphon discharge nozzle 18 of a toilet 20 so that the pressurized fluid is discharged through the drainage passage to release any blockages therein.

As best illustrated in FIG. 2, the plunger head 14 generally includes a carrier body 22, a coupling 24, a first 26 and second 28 flange, and a resilient foam body 30.

The elongated carrier body 22 has a liquid inlet end 32, a liquid outlet end 34, and an internal through passage 36 that extends along the carrier body and through the liquid inlet end 32 and liquid outlet end 34. In an embodiment, the elongated carrier body 22 is an elongated tubular member.

Located proximate to the liquid inlet end 32 is a coupling 24 that connects the internal through passage 36 to a source of pressurized liquid. The pressurized liquid travels the length of the internal through passage 36 and is discharged through the liquid outlet end 34 of the carrier body 22.

Encircling the liquid inlet end 32 of the elongated carrier body 22 is a first flange 26 that encircles the elongated carrier body 22 and projects outwardly from the elongated carrier body 22. In an embodiment, the first flange 26 is disposed at a longitudinally inward location from the liquid inlet end 32 and forms a seal shoulder. Encircling the liquid outlet end 34 of the elongated carrier body 22 is a second flange 28 encircling the elongated carrier body 22. The second flange 28, which also projects outwardly from the elongated carrier body 22, is longitudinally spaced along the carrier body 22 from the first flange 26. In an embodiment, the second flange 28 is flush with the liquid outlet end 34. In another embodiment, both the first flange 26 and the second flange 28 are dome-shaped.

A resilient foam body 30 extends between the first 26 and the second 28 flanges and encircles the elongated carrier body 22. The resilient foam body 30 may come in a variety of shapes that are sufficient in volume to allow the resilient foam body 30 to be positioned below the siphon discharge nozzle 18 and make a sealing contact with the drain so that all of the pressurized water may be discharged through the drainage passage 16, and none of the pressurized water will make its way into the siphon discharge nozzle 18. The first flange 26 prevents the foam body 30 from dislodging upwardly during insertion, and the second flange 28 prevents the foam body 30 from dislodging downwardly upon removal. The foam body 30 extends laterally, in an outward direction from the elongated carrier body 22, beyond the first 26 and the second 28 flanges to provide a sealing surface that is deformable to complement the interior shape of the toilet drain passage 16. In an embodiment, the foam body 30 is spherical in shape and extends laterally, in an outward direction from the elongated carrier body 22, beyond the dome-shaped flanges 26 and 28. Covering the resilient foam body 30, and optionally flanges 26 and 38, is a water-proof skin.

It may be understood that the elongated carrier body 22, the coupling 24, and the first 26 and second 28 flanges may be made of non-marring material, such as plastic, so as not to damage the porcelain toilet surface. The carrier body 22 may be made of one seamless continuous piece of material to be completely unitary.

The resilient foam body 30 may then be applied and adhered between the first 26 and the second 28 flanges and, further, to encircle the elongated carrier body 22 laterally, in an outward direction from the elongated carrier body 22. The application of the foam body 30, in this manner, prevents the foam body from sliding, distorting, and bunching along the elongated carrier body 22 and also prevents sewage from entering any part of the elongated carrier body 22, coupling 24, and flange 26 and 28 assembly. This assembly may further be immersed in a liquid plastic to form the skin covering 38. The liquid plastic may be infused with antimicrobial or antibacterial compounds.

Furthermore, the shape and material of the foam body 30 will allow the foam body 30 to conform to the contours of any toilet trap and bypass a toilet siphon jet to create a tight positive seal against the drain and, therefore, maximize the amount of pressure on the drain per square inch. This design, further, will not disturb the surface of the water in use, and will therefore prevent backsplash and bubbling of the water.

The assembly of the elongated carrier body 22, the coupling 24, and the first 26 and second 28 flanges may also be a single-use disposable assembly to avoid the necessity of cleaning the assembly. This may be beneficial, for example, in hospitals that may wish to maintain sanitary conditions.

As best illustrated in FIG. 1, the device further includes an elongated tubular wand 12 having opposite first 40 and second 42 ends. Extending between the first 40 and second 42 ends of the elongated tubular wand 12 is an internal fluid carrying passage 44, as seen in FIG. 2. As further illustrated in FIG. 2, the second end of the elongated wand 42 is connected to the coupling 24 that is located at the liquid inlet end 32 of the elongated carrier body 22. Provided between the elongated tubular wand 12 and the seal shoulder 46 of the first flange 26, there may be a circumferential o-ring to create a sealed connection. When the elongated wand 12 is connected to the coupling 24, the internal fluid carrying passage 44 of the elongated wand 12 and the internal through passage 36 of the carrier body 22 are fluidically connected. Connected to the first end 40 of the elongated tubular wand 12 is a trigger valve 48. The trigger valve, itself, also has a second coupling 50 for connecting the trigger valve to a source of pressurized liquid and is operable to control the flow of pressurized liquid through the tubular wand 12.

Therefore, it is understood that in order to clear a clogged toilet drain, a user would forcibly insert the foam body 30 into the drain. The shape of the foam body will distort and conform to the shape of the drain, thereby creating a tight seal. The user may utilize the second coupling 50 to connect the trigger valve 48 to a source of pressurized liquid. After the user has connected the trigger valve 48 to the source of pressurized liquid, the user may then insert the foam body 30 into the drainage passage 16 and operate the trigger valve 48 to release a flow of pressurized liquid through the tubular wand 12 and the internal through passage 36 to break up debris and clear the drain.

In an embodiment, as best illustrated in FIG. 3, the hydraulic plunger may further include a 45-degree coupling 52 connected between the second end 42 of the elongated tubular wand 12 and the coupling 24 located at the liquid inlet end 32 of the carrier body 22. In use, the 45-degree coupling will fluidically connect the internal fluid carrying passage 44 of the elongated wand 12 and the internal through passage 36 of the carrier body 22 at a 45-degree angle to facilitate the positioning of the carrier body 22 to be perpendicular to the toilet drain by a user.

In another embodiment, as best illustrated in FIG. 4, the hydraulic plunger includes a pulsator 54, which is known in the art. The pulsator 54, which may be located at either end of the elongated tubular wand 12, operates to induce a pulsating liquid flow exiting the internal through passage 36 of the carrier body 22 by providing a water valve which alternately opens in response to water pressure and closes in response to nonlinear restoring force for causing pulsed water flow to a point of use. This pulsating liquid flow may effectively loosen clogs and debris.
